To aZZ whom it may concern Be it known that I, WILLIAM S; HENRY, a citizen of the United States, and a resident of the city of Rochester, in the county of Monroe and State of New York, have in vented a new and useful Detector-Bar Clip, of which the following is a specification.

This invention relates more especially to clip devices used for supporting movable detector bars near or at railway track switches, and has for its main object to pro vide an inexpensive and efficient clip of this class which is preferably formed in one in tegral piece requiring little or no machining and adapted by an easily effected swaging of one or more of its parts by any ordinary unskilled laborer to closely clamp or look upon rail base flanges of varying thickness,

' thus assuring a secure fastening of similarly formed standard clips to the base flanges of railway rails having different sizes or weights and measurably relieving the clip fastening bolts of undue strains while holding the detector bar in proper operative relation to the rail.

Other objects and advantages will appear as the description of the invention progresses, and the novel features of the inven tion will be particularly pointed out in the appended claims.

Reference is made to the accompanying drawin s forming part of this specincation and in which Figure 1 is a side elevation of portions of a railway rail and adetector bar held thereto by the improved clip. Fig. 2 is an edgeelevation of the clip with its roller and the detector bar and rail in vertical transverse section. Fig.3 is an elevation showing the reverse side of the rail and the fastened clip, and Fig. 4 is fragmentary inner face view of the power portion of the clip as originally formed.

The improved clip is made preferably in one integral piece as a malleable iron casting having an inner chambered wall portion 1, comprising a comparatively narrow upper lug 2, adapted to fit the under face of the head 3, of a railway rail 4. This wall 1, also includes a broader lower portion having inclined flange or face portions 5, 5, which overlie the upper sloping face of the outer base flange 6, of the rail. The outer externally ribbed wall portion 7, of the clip connects at its lower end by a concaved base passed through th'eclip wall pin 14, passed through the outer bolt bearmg which preferably has a face lug 15 against which one edge facet of the bolt head rests to prevent tnrning of the bolt in its bearings and thus avoid shearing strains on the cotter pin. It is preferred to secure the clip to the rail 4, by two bolts 16, 16,

web and preferably having split locking washers 17, under their nuts 18. '.Ordinary hook-bolts 19, also may be passed laterally through holes-20, formed at lower opposite edge portions 21, 21', of the clip wall 1, where it joins the base web 8. The hook ends 22, of-bolts 19, engage the inner rail base flange 23, and these bolts preferably have split locking washers 2-1 under their tightened nuts '25. 7

It is not new to provide a clip of this class with two ccncaved or channeled lower 6X tensions through which the lower hookbolts 19, pass, and which bear by one or both upperedges upon the underside of the rail base flange 6. In this invention each channeled clip portion 26, has in its somewhat longer outer part a transverse open slit or slot- 27, made preferably at the point of junction of said pai't 26, with the hook-bolt bearing 21, as shown by full lines in F 2, and indicated by dotted lines in Figs. 3 and 4: of the drawings. Thus forming this slit or slot 27, provides a readily accessible exterior malleable lug or lip portion 28, which as originally formed, and preferably by coring in the molding process, projects tangentially upward and outward at an angle of approximately forty degrees, as shown in Fig. 4: of the drawing. This original lug formation provides for receiving between the clip flanges 5, and lugs 28, rail base flanges 6, which may vary considerably in thickness. After the clip is applied to the rail and is fastened thereto by the bolts 16,

T0 GENERAL RAILWAY 1, and the rail alone, or by thebolts 16, 19, the inclined lugs 28, 28, are forced upward and inward by a swaging hammer or other tool to bind the: tightly against the underside of the rail base flange 6, as 8 of the drawings. It thus is possible to use like standard detector bar clips upon railway track rails of varying siZe or weight,

or having base flanges 6, varying considerably in thickness. Forming the above. described slit or slot 27, assures that the entire and amply long free edge of the lug 28, may easily and quickly be swaged up tightly against the rail base flange 6, thereby giving a most effective clamping hold of the lug on the rail flange about from the hookbolt bearings 21, inward to the end ofthe channeled clip part 26. The swaging of the clip lugs 28, upwardly against the rail base flange may be done effectively by any ordinary or unskilled traclcliand or laborer after the clip is bolted to the rail, or the clip lug or lugs 28 may be finally swaged in the factory where the clips are made so as to snugly fit the base flange 6, of rails of any particular weight or size to which they are to be later fastened. The ,slitor slot 27, may be formed in only one of the two rearwardly projecting portions 26 of the clip which then would advantageously permit clamping of the clip to the rail by one lug 28, but forming the slot 27 in each of two clip portions 26, is preferred because it provides for clamping action of a clip lug 28, at two places, or near each of two hookbolts 19, thereby assuring a more substantial permanent connection of the clip to the rail which more fully relieves the clip fastening bolts from undue strains should an attempt be made to operate the bar while it is opposedby the wheels of a train passing over it.

Although I have particularly described the construction of one physical embodiment of my invention, and explained the operation and principle thereof; nevertheless, I desire to have it understood that the form selected is merely illustrative, but does Copies of this patent may be obtained for five cents each,

shown in Figs. 1 and not exhaust the possible physical embodiments of the idea of means underlying my invention.

lVhat I claim as new and desire to secure by Letters Patent of the United States, is:

1. A detector bar clip comprising a body portion shaped to lit between the head and flangeof a track rail and having a bottom portion projecting downwardly below the rail flange, said bottom portion having holes therein near its ends to receive members for fastening the clip to a track rail, a lug integral with said body portion near each end thereof and projecting inwardly underneath the rail fiangasaid'lug having a lippcrtiou adapted to be bent along a line extending transversely of the rail into contact with the under face of the flange of the track rail.

2. A detector bar clip comprising. a body portion shaped-to {it between-the head and flange of a track rail and having a bottom portion projecting downwardly below the rail flange, said bottom portion having holes therein near its ends to receive members for fastening the clip to a track rail, a lug integral withsaid body portion near each end thereof and projecting inwardly underneath the rail flange, said lug beingU-shaped in cross section to form two curved lips, one of said lips of each lug being separated from said bottom portion by a vertical slot and being capable of being bent-along a line eX tending transversely of the rail into contact with the under faceof the flangeiof the track rail.

A detector bar clip comprising a body portion shaped to litbetween theehead and flange ofatrack rail and having all-shaped portion integral therewith and projecting inwardly underneath the rail flange, one wall of saidiU-shaped portion having a vertical slot therein, thereby forming a lip capable of being bent alonga line extending transversely of ;the rail into contactwith the under face of the flange of thetrack rail.
